Abstract
It is made possible to mitigate appearance of the strap-shaped disturbance image and shift to the side lobe naturally. The sense of incongruity for an image viewed in a transitional zone is reduced by performing interpolation processing between parallax information pieces displayed on pixels associated with adjacent exit pupils.

A three-dimensional image display method for displaying a three-dimensional image on a display apparatus including a plane image display having pixels arranged in a matrix form, and an optical plate disposed so as to be opposed to the plane image display, the optical plate having exit pupils arranged in at least one direction to control light arrays from the pixels, the method comprising:
- generating an image for three-dimensional image display in which a plurality of pixels in the plane image display are associated as one of pixel groups with each exit pupil;
- setting each of the pixel groups to either a first pixel group which is n (where n is a natural number of at least 2) in the number of pixels in one direction of the pixel group or a second pixel group which is (n+1) in the number of pixels in one direction of the pixel group;
- disposing the second pixel groups between the first pixel groups discretely and at substantially constant intervals;
- and
- performing interpolation processing to mutually mix parallax information pieces of pixels located at both ends of the second pixel groups.
